When the sheet of paper is placed in position against the fingers J, one edgeiof the paper at vleast liesI beneath the metal strip N. This strip extends from beneath the roller Il rearwardly acrossl the barrel d of the impression platen and adjacent to the soft surface d2 thereof. Beneaththe strip N is a strip VN the forward portion of which curves downwardly around the upper part of the platen barrel, the two strips extending rearvardly in parallelism from a point adjacent to the highest line ofthe platen. Theparallel portions of the two strips are brought together at their outer edges and are 5V emerges from thc printing couple,--prevent.4

carried by a sheetnietal bracket N which is secured to the table plate A. ln the preferred form. the two strips N N and the bracket are a. single integral piece of sheet metal bent on itself, as shown in Fig. 5. This guiding structure is supplied at each f end of the raised nsurface to the impression platen. If the paper is 'of a full Width, each edge is guided by these strips. lf the paper is narrower than the full width, one edge is guided, which has been t'ound sufficient.

` The paper strippers and their combination with the paper feed are claimed in my H ppiieation Serial No. 839909, of which this division. The paper strippers are claimed herein in vcombination with the peper ejectiiig mechanism, with whiel'i-they also eoperate. l D "hen the movable Cain K has been adi'i ed and locked to properly time the paper feed according to the letter head on the paper, a rotation of the dru'm causes the pzliwr to be fed rearwardly between the drum a nd. platen, one or both edges of the paper paesini,r between the strips of the edge guida or guidi ln such operation, it sometiniest happens that the friction ot' thesheet f hiper develops sufficient frietional electricity to give it a tendency to cling to the printing drinn, so that as the paper emerges 'tronA the guiding strips, it is carried around ''owalrd the front of' the machine by the .printing drum, and; unless removed, will 'l ii pass through the printing mechanism. ns dillicully does not ordinarily occur, b t in ,hohl dry weather it sometimes happens,

. as shown in Fig. 2: This shaft is ,-airied at one end by a removable sind pt, extending into an opening in the sha it and at the other end by a screw p5, which projects into un opening in that end oi lhe shaft. This shaft p3 carries rollers P which project upwardly through openings in the tahlc A. l'lxtending horizontallyr across the machine near its rear edge is a rod Q. on Awhich are sliilably mounted arns R in the ioi-in of rages which carry lieelyjournaled rollers S adapted Ato,bear upon the rollers l. The paper being fed rearwardly in a suhstauv tially horizontal plane along the top of the table, runs between tlierollers S and P, which continue to guide it so that when the paper is treed from the guiding strips. it i'S not able to come up onto thc diuin aud cling thereto.

When the printing mechanism is used with narrow paper, as, for example, postal cards, only one'of the paper strippers engages such paper and only one of the endrnost rolls P of the ejector comes into action therewith. To take care ot' such narrow paper, T provide one or more interino diate rolls I. In the eniliodinient shown, there is one intermediate roll'l.) which is ordinarily sufficient, iis it is seldom desirable to print on paper materially less than But two rolls members R are slidable upon the rod Q, so

'that the two rolls S may be made to coperate with any two ot the rolls l), according to the position of the type F on the To furnish convenient means for shifting these rolls S, l. torni tailsl or extensions 'r on the members R by which they may be easily aken hold of by the fingers. Between the two earsof' the cage. which surround the rod Q, l place a split sleeve i" which engages this rod with sut'- ticient friction tol prevent accidental displacement of the cage R, while allowing it to be shifted when desired.

The cage R, as shown, is niade of a single piece of sheetinetal, bent toprcsent the following parts, namely; a smooth top surface, downturned sides which stiften it'and provide toi.' the bearings on the rod Q and for the pin ot' ythe roll S, the rearwardly prolriveting ai'mr, referred to, and ay forward ias
